高血压是动脉粥样硬化(AS)的危险因素之一。高血压如何引起AS的发生和发展,一直是人们关注的焦点。血流对血管的机械性作用分为两种:一种是血流和血管壁(内皮细胞)相互摩擦产生的剪切应力(shearstress;SS);另一种是血压作用于血管壁形成的环形张力(cyclicstretch;CS)。在生理条
Hypertension is one of the risk factors for atherosclerosis (AS). How high blood pressure causes the occurrence and development of AS has always been the focus of attention. The mechanical effects of blood flow on blood vessels are divided into two types: one is shear stress (shearstress; SS) generated by friction between blood flow and the walls of blood vessels (endothelial cells); and the other is the action of blood pressure on the ring Tension (cyclicstretch; CS).
